Matthew Cordle, 22, pleaded guilty Wednesday to aggravated vehicular homicide and to operating a vehicle under the influence of alcohol in Franklin County Court.

Cordle hit and killed Vincent Canzani while driving the wrong way on a highway while drunk. He was never charged, but confessed to the crime in a YouTube video posted on Sept. 3. It has been viewed more than 2.1 million times as of today.

Cordle faces two 8.5 year prison sentences. His attorney said he wants to remain incarcerated and start serving his time immediately.

"We hope the video he made will be seen around the world to raise awareness about drinking and driving," said his attorney. "Many millions of people have [already] seen this video."

"That's a lot of people!" the judge quipped, saying he had not seen the video but plans to watch it before the sentencing to get "more information" about the case.
